W thout departing from the spirit of the invention i The invention isillustrated in its preterretl embodiment 1n the Eigulte 1 isaperspeotive View of one corn8 Off: it box illustrating two. ed ecentwalls ighi piioved cornefconstniction. Fig. 2' is a t jagmentaryplanvie-W of one corner of the .ing boxes usually com'pfise a receptacleor trey, andja cover therefon'tyhicli are of; duplicate construction,zind'it will therefore be obvious that the present intention may beemployed in'theooi'ie'r or lid as Well as in the OX 1' ll'eeepteeleproper, and for the purpoee pf conyenience, theinvention 'Will bedescribed as employed in the/box or receptaclej, although it it" to bellIldQlIStOOd that the oo ne construction may be employed in varioushoxee'hovefs; and the like." i

The present box isformed from a blank of: paper, Cardboard or similarflexible stock, as usual, and einee the present invention resides in"the QOIIIQF consttuction, only" one corner of the box is illustitated,although it Wi l be evident that the 'present invention mz y beemfiiloyed "for each coTrner of' the box. The blank embodies the body' 1which forms the bottom of theboX tvhen the blank is folded, andthe bodyl of the'hlankhes pog-tionS which are fiolded upt'vlztltchto pi'oyidethe side Wallsof thebox, only two of 7 1513 being illustl' te In'eziltrymg outthe invention, reference being hadpeiitioulefhr to Fig. 2"wherein the e etmetion is illuetrated inblankfprhi, the

accoinpzthyihg '7 Qt the box secured together by means of the end of thewall 3 adjacent the adjacent wall 2 i provided with a tapered orapproxi-'mately triangular flan 4 projecting there from, the free end of theflap f being cut off, as at 5, and there being a fold line 6 between thewall 3 and the base of they flap 4.

The adjacent end of the wall 2 has a flap 7 projecting therefromadjacent the flap 4,

the two flaps being separated by a slit or cut extending to the cornerof the body or bottom 1 between the walls 2 and 3, and

.there is also a fold line 8 between the Wall a. 2:1and base of the flap7. The flap 7 is pro vided with a portion 9, which is foldable backagainst the outer'side of the body portion of the flap 7, upon thediagonal or oblique fold line 10 extending fromthe free end of the flap4 to that side of the base of the flap 7 remote from the flap 4:. Thatedge portion of the portion or supplemental flap *9 of the flap 7 whichis remote from the flap't, is provided with a recess or notch 11. Vhenthe blank is cut or struck from the stock, the flaps 4 and 7 may bereadily formed therein, and it will be noted that the flaps lie withinthe outline of the blank, in

ers is eliminated. V

" The flaps 4 and 7 are then bent or folded V *to provide theinterengageable portions or 35 members carriedby theadjacent ends of thei order that excessive or additional stock will .not be required. Thisis of advantage, since the waste incident to ordinarycorner'f'astenadjacent walls 2 and 3, and to this end'the flap 4 isfolded back or reflexed against the inner side of the wall 3 paralleltherewith,

and a staple or other securing element l2'is engaged through the basalportion of the m 4 and the wall 3 between the side edges of the saidflap. The staple or securing means 12 therefore holds the flap 4 inplace I adjacent the inner side of the wall 3 of the .box with the flapA: projecting inwardly or away from the respective end of the wall'3.

The portion 9 of the'flap 7 is folded back .against the outer side ofthe body portion of the flap 7, upon the fold line 10, the body portionof the flap 7 and the portion 9'being of triangular contour andcoinciding when they are folded'together, and a staple or securingelement 13 is then driven or engaged through the body portion of theflap 7 and the portion 9 of the said flap adjacent the apices ofthe saidportions Thus, the por Vtions of the flap 7 will be secured or held'together, and will provide a triangular pocket 14 whose mouth isdisposed adjacent the end of the wall 2 and which pocket opens outwardlyand away from the wall 3 of the box. It will be noted that the bodyportion of the flap 7 provides the inner side of the pocket 14, whilethe portion 9 of the said flap provides the. other side of the saidpocket, the outer side of the pocket or por tion 9 having the recess ornotch 11 adjacent and extending away from thevmouth of the pocket. Thedoubled flap extends at right angles from the wall 2.

The parts are thus secured together by the staples orsecuri'ng means '12and 13 at Y "fe'ctively secured; or locked together for holding thewalls2 and 3 together in a'fir m and eiiicient manneixf" To-atta'ch theside walls'2 and '3 together,they are folded up- "wa'r'dly at an angle'to the bottoml, and the parts are properly manipulated to, insert the land re'st against the inner side of the wall The flap t'is engagedwithin the pocket -14;'by swmging'thewall a-inward; toward i reflexed orbentback flap 4: into the pocket 14, whereby the pocket which is bentinwardly'will'snugly' receive the flap or tongue the bottom 1 afterthewall 3 has beenswung to erect position, perpendicular" within the:bottom 1, andwhich will bring the pocket 14 to such'a position adjacentor beyond the'free portion of the flap 4, to allow the flap l to bereadily received bythe pocket 14whenthe wall 2 is swung backto iiprig-ht or erect-position. The recess or notch 110f the portion 9 willreceive and accommodate the staple or'securing element 12, while thecutaway portion 5 of the flap 4 will prevent the flap 4 frominterfering'with the staple 13 at the apex ofthe pocket and in orderthat the members; of the'side walls may be properly and effectivelyinterlocked.

The corner of the box, when the side if walls are attached together,will be thor- Y "oughly substantial and will not be liable to break orburst; open when 'outward pressure is exerted against the side walls ofthe box.

Since the pocket Mof the side wall 2 is' en ga'ged over the flaplof'the'wall 3,with the 7 portion 9- projectingbetween the I flap 4: andjwa'll 3-beyond the staple 12, the wall2 cannot'swing outward, and"since the flap 4 of the wall3 is received in the pocket 14 of the wa112,the wall 3 cannot swing outward,'and

' as a consequence, the interengagement of the members of the walls' 2and 3 will efliciently 'hold the walls against separation, and the partswill not be liable to tear loose, as is frequentlythe' casewith theordinary fasteners of clothing andsimilar boxes.

f Particular attention is 'directed'to the fact that the doubledportionf79 which is located at the inner side of the wall 3' projectsangularly in'one direction from the wall 2,

and isprovided with the pocket'l opening in-the opposite directionat thebasal por bent back flap 4 at the end of the wall 3 and located at theinner side of said wall fitting in said pocket, will thereby hold saidWalls against separation, the flap 4; projecting in the same directionas the doubled portion.

From the foregoing, taken in connection with the drawing, the manyadvantages and capabilities of the present invention will suggestthemselves to those versed in the art and further comment is deemedunneces-' sary.

Having thus described the invention, what is claimed as new is 1. In adevice of the character described, a body having adjacent walls, onewall having a portion at the inner side of the other wall and projectingangularly in one direction from the first mentioned wall, and saidportion having a pocket opening in the opposite direction, the secondmentioned wall having a portion at its inner side projecting in the samedirection as the first mentioned portion and adapted to fit in saidpocket, whereby the walls are thereby held against separation andoutward movement.

2. In a device of the character described, a body having adjacent walls,one wall having a doubled portion at one end and at the inner side ofthe other wall and projecting angularly in one direction from the firstmentioned wall, said doubled portion providing a pocket opening in theopposite direction, the second mentioned wall having a portion bent backfrom one end and located at the inner side thereof, said bent backportion projecting in the same direction as the doubled portion andbeing adapted to fit in said pocket, whereby the Walls are thereby heldagainst separation and outward movement.

3. In a device of the character described,

7 Copies a body having adjacent walls, one wall having a doubled portionat one end and at the inner side of the other wall and projectingangularly in one direction from the first mentioned Wall, said doubledportion providing a pocket opening in the opposite direction, the secondmentioned wall having a portion bent back from one end and located atthe inner side thereof, said bent back portion projecting in the samedirection as the doubled portion and being adapted to fit in saidpocket, whereby the walls are thereby held against separation andoutward movement, a securing element engaged through the doubledportion, and a securing element engaged through the bent back portionand second mentioned wall, the doubled portion havinga recess foraccommodating the second mentioned securing element.

4. In a device of the character described, a body having a pair ofadjacent walls, one wall having a flap at one end bent backthereagainst, a securing element engaged through the basal portion ofthe flap and the said wall, the other wall having a flap at one endadjacent the aforesaid flap, the last mentioned flap being doubled upona diagonal fold line to provide a pocket for receiving the firstmentioned flap, the pocket and first mentioned flap being approximatelytriangular in contour, a securingelement engaged through the sides ofthe pocket adjacent the apex thereof, and one side of the pocket havinga recess for receiving the first mentioned securing element.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
